the script should work.
However it will generate an error when requesting it
through your browser since there is no output defined.

Two tips:

1) first output to the browser from any perl cgi script needs to be something like this:

print "Content-type: text/html\n\n";

2) when you get a 500 error in the browser, go look at the webserver's error log. it'll usually tell you what the perl error was including the line number.
